Joan L. BUGKLEY, F PORTLAND, OREGON ARBOR HUB Application filed May 115,

My invention relates to a device placeable upon a shaft or other cylindrical object upon which grinding wheels, saws,pulleys and any and all objects to be rotated by the shaft may 6 be mounted.

The invention in its preferred embodiment consists of a split member threaded upon its outer peripheral surface upon which clamping collars may be mounted, the object of which is to clamp the split member-upon the cylindrical member and r to simultaneously and fixedly position the object to be rotated between the clampingmembers.

Nly invention is intended for use in factories, machine shops and in any and all places where itfmay be foundfdesirable to clamp, or fixedlyposition, articles to be rotated upona shaft already installed and without the, dismantling of theshaft and the removal of hangers, pulleys-and the like to facilitate the placing of the device thereupon.

The device may be used as a splicing sleeve for connecting the ends of shafts or other obj ects togethcr and to place the same in position to be rotated by the shaft that is already in place.

The device may be utilized, in a modified form, for the mounting of saw collars thereupon to maintain a wobble saw thereupon to cut a kerf, the width of which, maybe precisely determined by the location of the collar and the sleeve.

A further object of my inventionconsists in providing a relatively cheap article of manufacture for use as aclamplng means for the positioning of saws, grinding wheels and l the like in place, upon arbors, shafts and upon other cylindrical objects.

A still further object of my invention consists in providing simple and efficient means comprised of a limited number of parts and one that may be accurately and cheaply finished for the purpose intended and that may be placed in position utilizing a minimum of time in doing so. v

With these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, the essential elements of which areset forth in the appended claims, and a pre 1930. Serial No. 452,658;

My invention is primarily intended for placement upon ashaft 1. j In its simplest form the device consists of a split sleeve 2 that anism illustrated in Fig. 5, the same being the mechanism illustrat- I is formed upon its, innerdiameter to sub-' slide freely upon the shaft 1 when not clamped. But by compressing the sleeves so as to decrease the: width of the slit 3 that runs posed upon the inner surface of the collars 5 and 6 is also relatively coarse, having a uni= form pitch with that of thethread 4 dispe sed upon the split sleeve 2.

A ny article may bemounted upon-the sleeve and between the respective collars as a grinding wheel 7, When -.pressure' -is plied upon the respective threaded collars -5 and 6 until a pressure develops uponthearti 'cle to be clamped therebetween asa grinding wheel' 7, the sloping surface ofthe internal .threadfof the threadedjcollars has a 313611- denc y to climbthe thread upon which the same is mounted and to thereby compress the split sleeve'2 upon the shaft 1.

; f The device may be used In the clamping of two shaft ends Sand ,9 together, *by the threaded flanges-being made to engage each other and-to compress the split'sleeve 10 about the respective endsoftheshaft. U

and forc'er- I For certain chara'cte'rsof work tain purposes it may be found desirableto place a spherical support 11' upon anarbor or 1 shaft: 12. The; spherical support is secured to the shaft by any suitable fastening means as by -a stud 13 being placed within the spherical member the inner end of which rests upon the shaft or arbor upon which the same is mounted. A collar- 14 may be placedfupon the arborand-a nut 15 be-threaded to oneend of the arborand the spherical support being clamped between thecollar and the n-ut. stud 13 is provided to prevent therotation of the shaft {on the arbor upon which thesame is mounted. In this form 'of construction the split sleeve maybe comprised of two-or more surface of each of thesections being adapted Threaded the objects primarily stated, it is to" be under:

stood that it is not intended to confine the in vention to the one form of embodiment hereshown' anddescribed, ,as it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow.

I What I 'claim,-is:

In adevice of theclass described, in combination with a shaft, a sphericalmember;

fixedly secured to the shaft, a plurality of sleeve section's c l isposedabout the spherical member and adapted to precisely' fit the "outer surface of the spherical membensaid sections havinga relatively coarse thread disposed upon their outer peripheral surface and which form, when together, a

completed threaded surface, collars thread;

able-about the sleeve sections, said collars when threaded upon the sleeve sections adapted to compress the sections upon the spherical memberand to maintain said sleeve so compressed.

in fixed relation to, the spherical member when i i 2. In adeviceoftheclass describedfin combination with a shaft, a spherical bearing 'disposed about the shaft, meansfor fixedly maintaining the spherical member upon the. V

shaft, a plurality of sleeve sections ad 7 just-ably disposed upon the spherical member, f

said sleeve sections being threaded upon their upper, surface, and a ,plurality of collars threadablydisposed about the sleeve sections adapted to maintain the said sections in fixed relation to the spherioal member. 7
